**FOR DETAILED INFORMATION SEE INSTALLATION & MAINTENANCE MANUAL **
1. Visually inspect water heater and components for damage and proper installation.
2. Check all electrical connections for tightness and proper voltage.
3. Check water heater tank to make sure it is full of water. (Remove air through T&P valve).
4. Pull nozzle assembly from burner and check gap settings on electrodes (see I&M).
5. While nozzle is removed, look inside through burner for obstructions.
6. Check fan rotation and purge air from oil pump by bumping motor contactor.
7. Check air shutter setting (guideline on burner tag).
8. Drill hole in vent pipe 12” to 24” from heater flue outlet but below draft regulator
9. (for analysis equipment).
10. Attach voltmeter to controller to record flame signal.
11. Connect a 300-psi gauge to pressure side of oil pump. Connect vacuum gauge to supply side of oil pump (15”
hg maximum allowed).
12. Set oil pressure to pressure on data decal (refer to I&M manual for two stage burner).
13. Check flame signal (should be in range called for by control 14-18 VDC or 4-6 VDC if UV).
14. Check vent draft in stack (should be negative .02” to negative .06” W.C.).
15. Perform flue gas analysis after achieving water temperatures above 120
º
F.
a) Net stack temperature should be 3 00
º
F - 400
º
F on high fire.
b) O2 should be from 4% to 7%. NOTE: Both low and high fire reading.
c) CO2 should be from 10.5% to 12.7%. NOTE: Both low and high fire reading. CO should not
exceed 200 PPM.
d) Smoke should be less than #2.
NOTE: A complete and proper start-up includes checking the operation of all controls and limits (i.e. airflow
switch, LWCO, thermostats, and modulating controls), and filling out the entire start-up report. All
